With the continuous deepening of the concept of precision diagnosis and treatment for lung cancer, how to achieve higher efficiency and accuracy in the screening, diagnosis, and treatment pathways in clinical practice has become an important issue that urgently needs to be overcome. The current clinical difficulty lies in the fact that despite continuous advancements in imaging and molecular diagnostic technologies, there are still limitations in manual efficiency and subjective experience when it comes to massive data analysis and multi-scale feature extraction. Artificial intelligence (AI), especially algorithm systems based on deep learning, is an innovative technology capable of deeply empowering medical big data. This method utilizes algorithms such as convolutional neural networks, combined with radiomics, pathomics, and multi-modal data fusion analysis, demonstrating immense potential in early precise detection and benign-malignant differentiation of pulmonary nodules, digital pathological subtype recognition and non-invasive prediction of driver genes, precise 3D surgical planning and automatic delineation of radiotherapy target volumes, as well as dynamic risk warning during follow-up. This innovative technology provides a brand-new solution for realizing intelligent and individualized lung cancer diagnosis and treatment models. This consensus, based on the latest evidence from evidence-based medicine and combined with the development trends in the AI field and real-world clinical needs, was ultimately formed by gathering the consensus opinions of multidisciplinary experts in radiology, pathology, thoracic surgery, and other fields. The main content covers the application specifications of AI in the three core scenarios of lung cancer screening, diagnosis, and treatment, the technical standards for data collection and algorithm validation, as well as the ethical and regulatory challenges faced at the current stage. It aims to clarify the applicable boundaries of AI as a clinical auxiliary decision support tool, providing scientific guidance and standardized exploration directions for peers currently engaged in or planning to carry out AI-assisted clinical diagnosis, treatment, and translation of lung cancer.

BACKGROUND:Upper lumbar spinal stenosis is a multifactorial degenerative disorder of the spine.For narrowing of the spinal canal in the upper lumbar region(L1-L4),surgical decision-making is particularly complex.Existing minimally invasive surgeries each have their own advantages and limitations.Currently,there are few reports on biomechanical comparison and finite element analysis of different surgical methods for the treatment of high lumbar spinal stenosis.OBJECTIVE:To analyze the biomechanical impact of endoscopic unilateral laminotomy for bilateral decompression,transforaminal endoscopic lumbar decompression,and cross-overtop decompression in the treatment of upper lumbar spinal stenosis using endoscopy,and to verify the reliability and effectiveness of these three surgical techniques in treating upper lumbar spinal stenosis,providing a biomechanical basis for clinical decision-making.METHODS:The CT images of the lumbar spine of a healthy volunteer were selected,and the finite element model M0 of the normal lumbar L1-L5 segments was established using Mimics,Geomagic,Solid works,and Ansys software.The L2-L3 segment,representing upper lumbar characteristics,was chosen.Based on this model,the surgical models for endoscopic unilateral laminotomy for bilateral decompression(M1),transforaminal endoscopic lumbar decompression(M2),and cross-overtop decompression(M3)were established.Using software,the changes in the range of motion of the entire lumbar segment and the maximum Von Mises stress of the intervertebral discs were simulated and evaluated for each group of models under six loading conditions:flexion,extension,left lateral bending,right lateral bending,left rotation,and right rotation.RESULTS AND CONCLUSION:(1)Compared with model MO,the range of motion in M1,M2,and M3 increased under all six conditions,with M1 showing a greater increase.(2)M1 and M2 demonstrated significant increases in range of motion under forward bending,extension,and right rotation,while the increase under other conditions remained below 7％.(3)Compared with model M3,model M1 exhibited slightly increased overall joint range of motion during extension and left bending,while no significant changes were observed in other aspects,and the L1-L5 lumbar segments did not reach an unstable state.(4)In model M1,the maximum Von Mises stress of the intervertebral discs increased most significantly under flexion and extension loading conditions.However,under left lateral bending,right lateral bending,left rotation,and right rotation loading conditions,the increase did not exceed 5％.(5)These findings suggest that due to the sagittal anatomical characteristics of the facet joints,the unilateral laminotomy for bilateral decompression technique,while decompressing,involves resection of more facet joints,which impacts overall segmental stability.The transforaminal endoscopic lumbar decompression technique is suitable for patients with foraminal stenosis but cannot achieve complete decompression for those with severe ventral central stenosis.The Cross-Overtop technique effectively enlarges the volume of the central canal and lateral recess,optimizing decompression,and shows unique advantages in treating upper lumbar spinal stenosis.

ObjectiveTo analyze the epidemiological characteristics of 8 major respiratory pathogens in influenza-like illness (ILI) cases with acute respiratory infections at fever clinics in Huangpu District, Shanghai from 2015 to 2024, and to provide a scientific basis for the prevention and treatment of respiratory diseases. MethodsA retrospective study was conducted in Huangpu District. Individuals meeting the case definition of ILI from 2015 to 2024 was registered. Their nasopharyngeal swabs were collected for pathogen detection. A total of 8 respiratory viruses were tested, including Influenza A virus (Flu A), Influenza B virus (Flu B), adenovirus (ADV), enterovirus/human rhinovirus (EV/HRV), human parainfluenza virus (HPIV), human coronavirus (HCoV), respiratory syncytial virus (RSV), and human metapneumovirus (HMPV). ResultsFrom 2015 to 2019, a total of 344 ILI cases were tested, of which 192 out of 344 cases (55.81%) were tested positive for single respiratory pathogen. From 2023 to 2024, 1 557 ILI cases were tested, with 572 out of 1 557 cases (36.74%) being positive for single pathogen. From 2023 to 2024, the positive rate of single pathogen in ILI cases was significantly lower than that in 2015‒2019 (χ²=42.66, P<0.001). Specifically, the positive rate of Flu A (χ²=74.43, P<0.001) decreased, while that of HPIV (χ²=8.66, P=0.003) increased, both with statistically significant differences. According to the seasonal pattern, the epidemic intensity of Flu A decreased in summer, while that of HPIV increased in summer and autumn. Demographic results showed statistically significant differences in the positive rates of EV/HRV between genders (χ²=22.38, P<0.001), with males exhibiting a higher positive rate than females. No statistically significant differences were identified in the positive rates of single pathogen among different age groups (χ²=4.42, P=0.110). Nevertheless, statistically significant differences were noted when comparing the positive rates of EV/HRV, Flu A, Flu B and HPIV across different age groups (P<0.05). EV/HRV was more commonly detected in the 15‒<25 age group (10.93%), while Flu A and HPIV had the highest positive rates in the ≥60 age group (21.24% and 4.77%). Flu B had the highest positive rate in the 25‒<60 age group (11.26%). 52.63% of cases with co-infections occurred during winter, with the primary pathogens involved being EV/HRV (9 cases) and HCoV (6 cases). The most prevalent combination of co-infection was Flu A with EV/HRV. ConclusionThe prevalence of respiratory pathogens among ILI cases from 2023 to 2024 exhibited notable fluctuations compared to that from 2015 to 2019. Therefore, influenza surveillance should be strengthened, and attention should also be paid to the prevalence of respiratory pathogens such as HPIV. These findings have profound implications for future research, surveillance, vaccine planning, and public health policy making.

AIM: To evaluate safety, efficacy, visual quality, and patient satisfaction after optimized monovision Q-value-customized femtosecond laser-assisted in situ keratomileusis(FS-LASIK)for myopia, astigmatism, and presbyopia. METHODS: This prospective study enrolled patients suffering myopia, astigmatism, and presbyopia. At 1 y post operation, uncorrected distance, intermediate and near visual acuity(UDVA, UIVA, UNVA), refraction, corneal higher order aberrations(HOAs), Q value, objective visual quality, and near stereoacuity were evaluated. The impact of surgery on patients' living quality and their satisfaction were evaluated based on National Eye Institute Refractive Error Quality of Life Instrument(NEI RQL)scores at 1-year follow-up.RESULTS:The study enrolled 36 patients(72 eyes)including 12 males(33%)and 24 females(67%)with an average age of 46.03±3.60(range 40-53)y. One year postoperatively, 97% of patients achieved binocular UDVA of 1.0 or better, 89% achieved UIVA of 0.63 or better, and 97% achieved UNVA of 1.0 or better. The spherical equivalent refraction(SE)in dominant eye within ±1.00 D was 100%. SE in non-dominant eyes was uncorrected compared with the preoperative target correction, with a mean difference of -0.27±0.34 D before and after surgery(P<0.001). while in the non-dominant eyes, the anterior corneal Q-value within the 5 mm zone increased negatively compared with the preoperative value(-0.33±0.24 vs -0.21±0.09, P<0.001). In the non-dominant eye, spherical aberration and longitudinal spherical aberration were lower than preoperative values(both P<0.001). Besides, there were no significant changes in objective scatter index(OSI), modulation transfer function cutoff frequency(MTF cut off)and Strehl ratio(SR)in both dominant and non-dominant eyes(all P>0.05), and the near stereoacuity was better after surgery(P=0.007). Additionally, the patient satisfaction rate with the surgery was 94%, the satisfaction rates for UDVA and UNVA were both 98%. The 11% of patients required to wear low-diopter glasses when driving at night.CONCLUSION:Optimized monovision Q-value-customised FS-LASIK is a safe and effective procedure for correcting myopia, astigmatism, and presbyopia. It provides favorable subjective and objective visual quality and high patient satisfaction. The under correction in non-dominant eyes is observed, indicating the further optimization of nomogram is needed.

[Objective] To study on the genotyping of a sample with inconsistent forward and reverse serological tests, and to conduct a pedigree investigation and molecular biological mechanism study. [Methods] The ABO blood group of the proband and his family members were identified using blood group serological method. The ABO gene exon 1-7 of samples of the proband and his family were sequenced by Sanger and single molecule real-time sequencing (SMRT). DeepTMHMM was used to predict and analyze the transmembrane region of proteins before and after mutation. [Results] The proband and his mother have the Bw phenotype, while his maternal grandfather has ABw phenotype. The blood group results of forward and reverse typing of other family members were consistent. ABO gene sequencing results showed that there was B new mutation of c.3 G>C in exon 1 of ABO gene in the proband, his mother and grandfather, leading to a shift in translation start site. DeepTMHMM analysis indicated that the shift in the translation start site altered the protein topology. [Conclusion] The c.3G>C mutation in the first exon of the ABO gene leads to a shift in the translation start site, altering the protein topology from an α-transmembrane region to a spherical signaling peptide, reducing enzyme activity and resulting in the Bw serological phenotype.

Objective:To reveal the differences in the transcriptome maps of brain tissues in mice subjected to Flash irradiation and conventional dose rate irradiation with electron beams and to explain the biological effect and mechanisms of Flash irradiation from multiple perspectives.Methods:Following the principle of grouping based on approximate body weights, 36 female C57BL/6J mice were divided into three groups, i. e., the control, conventional dose rate irradiation (CONV), and Flash irradiation (Flash) groups, with 12 mice in each group. Both the CONV and Flash groups received a single 15 Gy whole-brain irradiation with 9 MeV electron beams. At 3 d post-irradiation, the whole-brain tissue specimens were collected for hematoxylin-eosin (HE) staining to observe pathological changes. At 1, 3, and 10 weeks post-irradiation, the motion function, cognitive ability, depression level, and spatial memory capacity of the mice were assessed using ethology. At 1 and 10 weeks after behavioral experiments, brain tissue samples were collected and snap-frozen in liquid nitrogen for reference-based transcriptome sequencing. Accordingly, the differences in the transcriptome maps of radiation-induced brain injury between CONV and Flash groups were analyzed.Results:The HE staining-based pathological result revealed that compared to the CONV group, the Flash group exhibited reduced glial cell hyperplasia and inflammatory cell infiltration in brain tissues. Ethological research result at 1 week post-irradiation showed that the CONV group manifested a significantly decreased total traveled distance compared to the control and Flash groups ( t = 5.51, 2.38, P < 0.05) and a significantly increased immobility time compared to the control group ( t = 3.60, P < 0.05). Ethological research result at 3 weeks post-irradiation indicated that compared to the CONV group, the Flash group displayed significantly alleviated cognitive impairment ( t = 3.35, P < 0.05) and reduced depression levels ( t = 2.39, P < 0.05). Ethological research result at 10 weeks post-irradiation demonstrated that the CONV group showed the worst cognitive performance, significantly differing from the control group ( t = 4.53, P < 0.05). Transcriptome sequencing result revealed that besides immune-related pathways, the Flash group also exhibited multiple upregulated metabolic pathways and fibroblast growth factor (FGF)-related pathways compared to the CONV group. Conclusions:Compared to conventional dose rate irradiation, Flash irradiation can effectively alleviate radiation-induced brain injury in mice. This effect is associated with various metabolic pathways (including amino acid metabolism) and FGF-related pathways besides immune pathways.

Objective To analyze the incidence of cardiovascular events among patients with comorbid chronic obstructive pulmonary disease(COPD)and hypertension(HTN),as well as to identify the associated influ-encing factors.Methods A retrospective analysis was conducted on patients diagnosed with primary hypertension(HTN group,n=64),chronic obstructive pulmonary disease(COPD group,n=64),and concomitant primary hypertension and COPD(combined group,n=64)at our hospital between December 2021 and January 2025.Cardiovascular event incidence,pulmonary function parameters-including forced vital capacity(FVC),forced expiratory volume in 1 second(FEV1),peak expiratory flow(PEF),and percent predicted FEV1(FEV1%pred)-and blood pressure levels(systolic blood pressure[SBP],diastolic blood pressure[DBP])were compared across the three groups.Kaplan-Meier curves were constructed to illustrate and compare the cumulative incidence of cardiovas-cular events.Covariance analysis was performed to assess the impact of hypertension on pulmonary function,and Cox proportional hazards regression was employed to identify factors associated with cardiovascular outcomes.Results The total incidence rate of cardiovascular events in the HTN group was 14.06%,which was significantly lower than that in the COPD group(29.69%)and the combined HTN-COPD group(48.44%)(P<0.05).A highly significant difference was observed in the cumulative incidence rates across the three groups(P<0.05).Specifically,the COPD group exhibited a higher cumulative incidence than the HTN group(P<0.05),while the combined group showed the highest incidence,exceeding both the COPD and HTN groups(P<0.05).Pulmonary function parameters-including FVC,FEV1,PEF,and FEV1%pred-were significantly higher in the HTN group compared to both the COPD and combined groups(P<0.05).Moreover,these indices were also higher in the COPD group than in the combined group(P<0.05).Systolic and diastolic blood pressure(SBP and DBP)levels in the combined group were significantly elevated compared to both the HTN and COPD groups(P<0.05),and SBP and DBP in the HTN group were higher than those in the COPD group(P<0.05).After adjusting for potential confounders,the intergroup dif-ference in FVC remained statistically significant(P<0.05),and the effect of group on FEV1%pred was particularly robust(partial η2=0.754,P<0.05).Compared with patients without cardiovascular events,those who experienced events differed significantly by disease type(P<0.05).The proportions of patients with HTN alone and HTN com-bined with COPD were higher in the event group than in the non-event group(P<0.05).Additionally,FVC and FEV1%pred were lower in the event group,whereas SBP and DBP were higher(all P<0.05).Multivariate analysis identified disease type,FEV1%pred,and SBP as independent predictors of cardiovascular events(P<0.05).Deci-sion tree analysis further highlighted that the coexistence of HTN and COPD constitutes a critical determinant in cardiovascular risk stratification.Conclusions The incidence of cardiovascular events in patients with COPD com-bined with HTN was significantly higher than in those with either condition alone.Furthermore,the coexistence of these diseases,along with impaired lung function(as indicated by reduced FEV1%predicted)and increased SBP,were independent risk factors for cardiovascular events.

Aim To investigate the effect of chrysoeriol on pulmonary vascular remodeling in pulmonary hyper-tension by animal experiments combined with cell ex-periments,and to explore its potential therapeutic tar-gets by network pharmacology.Methods The target of chrysoeriol was collected in Targetnet,SEA and SwissTargetPrediction database.Pulmonary arterial hy-pertension(PAH)targets were collected in the Dis-GeNET and GeneCards databases,and PPI network map was drawn in the STRING database,and key tar-gets were screened.The GO and KEGG pathway en-richment analysis was carried out through DAVID data-base and Weishengxing platform.AutoDock software was used for molecular docking of key core targets.The PAH model of rats was constructed,and the pulmo-nary hemodynamics and vascular remodeling were de-tected by echocardiography,HE and Masson staining.Primary pulmonary smooth muscle cells were extracted,and the effects of drugs on pathway proteins were de-tected in vitro.Results The results of network phar-macology showed that chrysoeriol exerted therapeutic effects on pulmonary hypertension by affecting key tar-gets such as AKT1,SRC,EGFR,MMP9 and gsk3 β,and signaling pathways such as EGFR and PI3K-AKT.Molecular docking showed that chrysoeriol had good binding ability with 5 key target genes.Animal experi-ments showed that the pulmonary hemodynamic func-tion of PAH rats was significantly improved after ad-ministration of chrysoeriol.The remodeling of small pulmonary arteries was significantly reduced.Cell ex-periments showed that chrysoeriol could inhibit the ex-pression of proliferation,migration and phenotypic transformation genes.Conclusion Chrysoeriol may play a role in the treatment of pulmonary hypertension through multiple targets.

Objective:To investigate the predictive value of transabdominal uterine electromyography for pre-term labor after tocolysis in women with threatened preterm labor.Methods:A total of 48 pregnant women at 28-34 weeks of gestation diagnosed with threatened preterm labor and admitted to The Fourth Affiliated Hospital of Soo-chow University from January to September 2023 were included.According to the response to tocolysis and whether the pregnancy was prolonged for at least 48 h,women were divided into two groups:non-preterm birth within 48 h(n=35)and preterm birth within 48 h(n=13).Uterine electromyography parameters and difference were compared before and after tocolytic therapy in two groups.Univariate Logistic regression was performed to predict the related factors of preterm birth within 48 h after the using of tocolysis in pregnant women with threat-ened preterm birth by uterine electromyography,and receiver operating characteristic(ROC)curve was per-formed to evaluate their performance.Results:Compared to before treatment with tocolysis,after therapy,in the non-preterm birth within 48 h group,significant reductions in contraction frequency,area,duration and amplitude were observed(P<0.05).In the preterm birth within 48 h group,only contraction frequency decreased significant-ly(P<0.05).Univariate Logistic regression indicated that contraction frequency,contraction duration,and contrac-tion area were predictive factors for premature birth within 48 h after tocolysis(P<0.05).When the duration of u-terine contractions lasting for 104.55 s or more the sensitivity and specificity of predicting premature birth within 48 h are 92.3％and 68.6％,respectively.Conclusions:Uterine electromyography may predict the premature birth within 48 h after tocolytic treatment in preterm labor,which may provide reference for subsequent corticosteroid therapy or transfer of high-risk pregnant patients.
